Here are a couple of patches to make gcc-3.4.6/libobjc compile on my system:
Gentoo on an AMD box with gcc-3.3.5. The problem was that the configure script
was failing with this error:
checking for gthread cflags... configure: error: not found
because there is nothing to be found about GTHREAD in ../Makefile, contrary to
what is said in the file THREADS:

If you are compiling libobjc as part of GCC, the thr-objc.c backend is
always used; this backend uses GCC's gthread code. The thread system
is automatically configured when GCC is configured. Important: make
sure you configure GCC using `--enable-threads' if you want threads !

I configured gcc-3.4.6 with --enable-threads so I guess this documentation is
outdated.
